The Strait of Messina Bridge Project, if completed, would stand as one of the landmark bridges of the 21st century. It would be the longest suspension bridge ever built. The Strait of Messina divides the island of Sicily from Calabria in southern Italy, and is 3 km wide. While the overall length is not a big problem, the economics, water depth, wind, and earthquakes all have to be accounted for. To avoid the problem of the deep water, the solution was to design the longest suspension bridge ever...

The skies over Hispaniola opened up on May 24, 2004, and poured as much as 10 inches (25 cm) of rain within a 24-hour span onto an already rain-soaked island that had received as much as 10 inches of rain over the previous week. The torrent triggered flooding and mudslides that ran swiftly down the northern and southern flanks of the Massif de la Salle, straddling the border between Haiti and the Dominican Republic...

../Features/ArcticIce/Images/temp_anomaly_lrg.mov large (9.6 MB Quicktime) Arctic sea ice that survives the summer and remains year round -- called perennial sea ice -- is melting at the alarming rate of 9 percent per decade, and early findings suggest that summertime melting of Arctic sea ice in 2003 is on pace to rival last year's low. Satellite measurements show that most of the Arctic warmed significantly in the 1990s compared to the 1980s...

The 6,194-meter-tall (20,320-foot) Mt. McKinley is a towering double-peaked mountain in the middle of the Alaska Range, made all the more impressive for rising thousands of feet above its neighbors. As the tallest mountain in North America, it is one of the world's Seven Summits (the tallest mountains on each of the seven continents). The plains immediately to its north, at an elevation of 600 m (2,000 feet), give Mt...

|The Infant Island of Surtsey, Iceland: Image of the Day - NASA -- Image by Robert Simmon, SSAI/NASA GSFC, based on data copyright www.geoeye.com/ GeoEye|
On November 14, 1963, an Icelandic fisherman noticed a plume of smoke rising from the open water. Within a day, Surtsey, a new volcanic island, had formed off the southern coast of Iceland. By 1965, plant life had colonized the relatively flat southern portion of the island, which is also visited by migratory birds and seals. The eruption lasted until 1967, forming an island with an area of 2.7 square kilometers (1.04 square miles)...

|Northern Forest Affected by Global Warming: Image of the Day - NASA -- (Map adapted from figures provided by Scott Goetz, www.whrc.org/ Woods Hole Research Center )|
By most predictions, the Northern forests that cover much of North America, Europe, and Asia, should be getting greener. Scientists have always thought that plant growth in the world's Northern forests was limited by temperature. Arctic summer provides a brief period in which plants can develop before the cold of winter ends the growing season. Over the past century, however, temperatures have gone up and the length of the growing season has increased, nearly doubling in sections of Alaska...

|Hurricane Iris Hits Belize : Image of the Day - NASA -- Image courtesy Marit Jentoft-Nilsen, NASA GSFC rsd.gsfc.nasa.gov/rsd/ Visualization Analysis Lab|
Hurricane Iris hit the small Central American country of Belize around midnight on October 8, 2001. At the time, Iris was the strongest Atlantic hurricane of the season, with sustained winds up to 225 kilometers per hour (140 mph). The hurricane caused severe damage--destroying homes, flooding streets, and leveling trees--in coastal towns south of Belize City. In addition, a boat of American recreational scuba divers docked along the coast was capsized by the storm, leaving 20 of the 28 passenge...

From its headwaters in Germany's Black Forest, the Danube winds its way through ten European countries to drain into the Black Sea. For much of its course, the river moves lazily through wide valleys, but as it enters the border region between Romania and Serbia, its banks narrow into a series of high cliffs. Here, the river carved a passage through the lower Carpathian Mountains to its north and the Balkan Mountains to its south, creating a series of four steep gorges...
